Adjusting the Angle Adjustable (vertical/horizontal) Actuator
• Using the angle adjustment screw (M3 hexagon socket set screw), the actuator
angle can be adjusted up to 20°(refer to dimensions).
• The larger the actuator angle, the smaller the applicable radius of the door swing.
After installing the actuator, open the door. Then adjust the actuator angle so that the
actuator enters the entry slot of he safety switch properly.
• After adjusting the actuator angle, apply loctite or the like on the adjustment screw to
prevent loosening. Use screw locking agent that is compatible with the base material.
Base: PA66 (66 nylon) of glass reinforced grade
Angle adjustment screws: stainless steel

HS9Z-A61, HS9Z-A62 ACTUATOR
• When there is a displacement of safety switch and actuator, the actuator may hit the
entry lot of safety switch hardly, thus damaging the entry slot and actuator. The
rubber cushions on the HS9Z actuator prevent the actuator from damaging the entry
slit by absorbing the shock with movement flexibility. Do not, however, exert exces-
sive shocks, otherwise the failure of safety switch may be caused.
• The rubber cushions may deteriorate depending on the operatiing environment and
conditions. Immediately replace the deformed or crasked rubber cushions with new
ones.

Identification of terminal numbers
• When wiring, the identification of terminal number on each contact is made by
colored wire.
• The following shows a safety (main) contact and an auxiliary contact for three
contacts and two contacts types.
• When wiring, cut unnecessary wires such as dummy insulator (black) and / or
unused wire to avoid incorrect wiring.

Precautions for Operation
Installation
• Do not apply an excessive shock to the safety switch
when opening or closing the door. A shock to the
safety switch exceeding 1,000 m/s
2
may cause
failure.
• Provide a door guide, and ensure that force is applied
on the safety switch only in the actuator insertion
direction.
• Entry of foreign objects in the actuator entry slot may
affect the mechanism of the switch and cause a
breakdown. If the operating atmosphere is contaminated, use a protective cover to
prevent the entry of foreign objects into the switch through the actuator entry slots.
• Make sure to install the product in a place where it cannot be damaged. Make sure
to conduct a proper risk assessment evaluation before using the product, and use a
shield or a cover to protect the product if need be.
• Do not fasten and loosen the conduit at the bottom of the safety switch.
• When wiring, make sure that liquid such as water and oil dose not intrude from the
tip of cable.
• When bending cable at wiring, secure the cable radius of 40mm at the minimum.
• Be sure to use the dedicated actuator only, and do not operate the HS6B safety
switch with anything other than the dedicated actuator. Otherwise, the safety of the
system may not be maintained.

When the torque is not enough to recommended screw tightening torque, make
sure that the screw do not become loose by using adhesive sealants etc. to
keep right operation and mounting positioning.

WARNING
• Turn off the power to the safety switch before starting installation, removal, wiring,
maintenance, and inspection on the safety switch. Failure to turn power off may
cause electrical shocks or fire hazard.
• Do not disassemble or modify the switch. Also do not attempt to disable the safety
switch function, otherwise a breakdown or an accident will result.
CAUTION
• HS6B Series Safety Switches are Type 2 low-level coded interlocking devices (EN
ISO / ISO14119). The following system installation & mounting instructions are EN
ISO / ISO14119 requirements to prevent function failure from the interlock switch.
1. Using permanent fixing methods (e.g. welding, rivets, special screws...etc) to
prevent dismantling or de-positioning of the interlock device. However, perma-
nent fixing methods are not an adequate solution if you expect the interlock
device to fail during the machinery lifetime, or if you need to replace the prod-
uct in quick manner. In these situations, o her measures (see 2.) should be put
in place to reduce the risks of function failure.
2. At least one of the following measures should be applied to prevent function
failure.
(1)
Mounting the interlock device in a place out of reach from workers
(2) Using shielding protection to prevent physical obstruction of the device
(3)
Mounting the interlock device in a hidden position
d vice
(4) Integrate status monitoring & cycling testing of the device to the control
system to prevent product failure.
• Regardress of door types, do not use the safety switch as a door stop. Install a
mechanical door stop at the end of the door to protect the safety switch against an
excessive force.
• Mount the actuator so that it will not hit the operator when the door is open,
otherwise injury may be caused.
• Pay attention to the management of spare actuator. Safety function of door safety
switch will be lost in case the spare actuator is inserted into the safety switch.
Ensure that the actuator is firmly fastened to the door (welding, rivet, special
screw) in the appropriate location, so that the actuator cannot be removed easily.
• Do not cut or remodel the actuator, otherwise failure will occur.
• If multiple safety components are wired in series, the Performance Level to EN
ISO 13849-1 will be reduced due to the restricted error detection under certain
circumstance.
• The entire concept of the control system, in which the safety component is
integrated, must be validated to EN ISO 13849-2.
